4 Overview The U9925-GEM (40995G-03) Gateway Expansion Module is a fixed-mounted device that allows two, three, or four gateways to be connected together, creating a wireless-only intercom of up to 16-users. Compatible gateways include U9922-G38 (40995G-01) and its EU equivalent. Figure 1: Overview of Gateway Expansion Module 19542P-91 (12-13) 2 of 5

5 Installation Power The U9925-GEM is powered using the C98-20PW 20-foot power cable. This cable may be cut to the required length. Connect the flying leads RED (+) and Black (-) to an 8-32VDC power source, fused at 2A. Attach the molded connector end of the cable to the POWER input on the U9925- GEM. RED BLACK/SHIELD To 2 amp circuit breaker/fuse Figure 2: C98-20PW Power Cable The C98-20PW is supplied with a fuse kit which may be used if a 2A fused power source is not available. See Figure 3 below for assembly details. Figure 3: Fuse Kit Assembly 19542P-91 (12-13) 3 of 5

6 Gateway Connection Connect up to four wireless gateways to the SYSTEM ports on the U9925-GEM using the model C99-20MS Interface Cable (P/N: 40935G-05). To connect the cable to the U9925-GEM: 1. Align keyways on the connectors and push 2. Firmly turn collar clockwise until it locks into place 3. Pull back gently on the cable to ensure connector is properly locked Operation The U9925-GEM Gateway Expansion Module does not have a user interface and does not require configuration. Once installed and power is applied all connected gateways will function as if they were connected to an intercom. Communication between wireless users connected to all gateways is now possible. Up to 16 users can communicate with one U9925-GEM. Refer to the appropriate wireless gateway instruction manual for additional information. Note: When the Expansion Module is used with multiple U9922-G38 gateways, a C3821 Radio Interface Cable (P/N 18747G-06) must be connected to each gateway requiring radio transmit/receive capability. Any radio connected to one Gateway will be monitored by all users within the U9925-GEM system regardless of the Gateway to which they are connected. However, radio transmit will only be provided to those users linked to a Gateway which is in turn connected to the radio via a C3821 cable. For ease of radio install, multiple C3821 cables may be wired to individual MS connectors (P/N 18352G-17) and collected through a U3805 Radio Junction Module (P/N 41035G-01), which can then route a single C3821 directly to the radio. See C3821 Installation/Operation Instructions (doc. # 19510P-87.) 19542P-91 (12-13) 4 of 5
